Passengers using Edinburgh airport last month grew by 4.1% to more than 965,000 over March 2016.
The performance represents the busiest March for a Scottish airport, with international passenger numbers performing particularly strongly with 5.5% growth year-on-year to 520,333.
Domestic numbers were up by 2.5% to 444,958, helped by the start of four times daily flights by Flybe to Heathrow in the month.
Airport chief executive, Gordon Dewar, said: “March’s passenger figures underline Edinburgh airport’s growing international ambitions and ongoing demand to fly to and from this great city.
“We have seen another solid increase in the number of international passengers which highlights the ever-increasing draw of Edinburgh as a global destination.
“An increase in visitors to the city stimulates the economy, creates new jobs and offers direct international links for all of Scotland.”
He added: “As we move into the final few weeks of our public consultation on airspace change I would urge everyone in our neighbouring communities with a view on our preferred flight path options to respond before our consultation closes on May 7.”
